DiamondBack Bed Cover. All aluminum. Locking and weather sealing. I know for sure it fits all GM pickups from 99-07 with the 6' 7" bed. These retail new for 2600 bucks plus shipping and are currently 6-8 weeks on backorder. This one is used, but only for 1 summer. Rhino lined top, tough enough to park a quad or sled on top. Seals tight enough to run through a car wash and keep your bed dry inside. Sold the pickup it was bought for and no longer have a use for it. Pick up Minot and I can help you install it. Trades accepted for 8x170 wheel and wheel setup only.
